Do not judge me by my successes, judge me by how many times I fell down and got back up again.

There is great value in disaster. All our mistakes are burned up. Thank God we can start a new.

Each time you fail, you have eliminated another wrong option.

I didn't fail 1000 times. The light bulb was an invention with 1000 steps.

I never view mistakes as failures. They are simply opportunities to find out what doesn't work.

A failure teaches you that something can't be done-that way.
